Calculate the half-life at 100 molecules, 50 molecules and 25 molecules for a 1st order reaction and for a 2nd order reaction. Use k = 0.100 with appropriate units for both the 1st order and the 2nd order. Compare and contrast the half-life values for the 1st and for the 2nd order values determined in the above question.  (this is what I need help with).
